OVERVIEW
Group total recordable injury frequency rate (TRIF) at the quarter end was 5.9 (30 June 2018: 5.5). The focus continues to be on improving the safety culture and embedding critical controls at operational sites.
Group gold production for the September 2018 quarter was 200,218 ounces (Jun qtr: 202,254oz) at an AISC of A$885/oz (Jun qtr: A$846/oz). Using the average AUD:USD exchange rate for the quarter of 0.7315, Group AISC equated to US$647/oz – ranking Evolution as one of the lowest cost gold producers in the world.
Evolution delivered operating mine cash flow of A$196.9 million (Jun qtr: A$221.9M) and net mine cash flow of A$129.3 million (Jun qtr: A$136.0M). Group capital expenditure was A$67.7 million (Jun qtr: A$85.9M).
As at 30 September 2018, gross debt outstanding under the Senior Secured Syndicated Term Facility D was A$375.0 million. Net bank debt stood at A$78.2 million (Jun qtr: A$71.8M). A fully franked dividend of 4 cents per share equating to A$67.7 million was declared and paid during the quarter. The Group cash balance decreased to A$296.8 million (Jun qtr: A$323.2M).
Ernest Henry delivered a standout operating performance producing 25,638oz at an AISC of A$(617)/oz generating net mine cash flow of A$53.8 million.
The capital projects at Cowal, which are a key driver of Evolution’s organic growth, progressed well during the quarter. Material movement in the Stage H cutback was slightly ahead of plan. The Float Tails Leach project, which is expected to increase recoveries by 4 – 6%, is on schedule for commissioning in the December 2018 quarter. Subsequent to the end of the September quarter Cowal also received regulatory approval to expand the plant’s processing rate by 31% from 7.5Mtpa to 9.8Mtpa.
Successful drilling at Cowal’s GRE46, GRE46 South and E41W continues to highlight the high grade nature of this mineralised system. Strong results were also returned from Mungari drill programs including high grade intersections at Scottish Archer and Castle Hill.
In July 2018 Evolution signed an agreement with Norton Gold Fields to restructure ownership of the Castle Hill gold deposit. Evolution’s now owns 100% of this project with Ore Reserves of 236,000 ounces which will provide a material extension to the operating life at Mungari.
In September 2018 Evolution entered into an earnin joint venture agreement with Andromeda Metals over the ~520km[2 ] Drummond exploration project. The project is situated close to Evolution’s Mt
Carlton gold mine and leverages the Company’s expertise in epithermal gold deposits.
Evolution’s Investor Day held in Sydney on 4 September provided a comprehensive Company update including a three-year production and cost outlook. An ‘on demand’ webcast can be viewed at: evolutionmining.com.au/webcasts-media/
December 2018 quarter gold production is expected to be between 185,000 – 195,000 ounces.

OPERATIONS
Cowal, New South Wales (100%)
Cowal delivered another strong quarter producing 61,260oz of gold at an AISC of A$958/oz (Jun qtr: 63,777oz, AISC A$976/oz). Plant throughput of 1,921kt was achieved. TRIF increased from 3.3 to 4.0 and was down 27% year-on-year from 5.5.
Mine operating cash flow for the quarter was A$52.8 million. Net mine cash flow was A$24.0 million (Jun qtr: A$5.8M) post sustaining capital of A$9.3 million and major capital of A$19.5 million. Major capital was associated with growth projects including the Stage H, Float Tails Leach (FTL) project and early works on the new Integrated Waste Landform tailings facility.
Stage H material movement is slightly ahead of plan. Mining activities have moved from free digging of the oxides into fresh rock that now requires drill and blast.
The FTL project is on track to be fully commissioned during the December 2018 quarter.
Subsequent to the end of the quarter, regulatory approval was granted for the Modification 14 development application. Key aspects of this modification include increasing plant processing rate from 7.5Mtpa to 9.8Mtpa and the use of an Integrated Waste Landform as a tailings solution for the life of mine. This approval is an important milestone toward achieving a sustainable 300,000oz per annum production profile.
Mungari, Western Australia (100%)
Mungari produced 35,120oz of gold at an AISC of A$1,120/oz (Jun 2018 qtr: 30,169oz, AISC A$1,235/oz). TRIF decreased from 8.5 to 7.5 with one Medical Treatment Injury (MTI) occurring during the quarter.
Mine operating cash flow for the quarter was A$22.8 million (Jun qtr: A$11.8M). Net mine cash flow was A$17.4 million (Jun qtr: A$3.3M) post sustaining capital of A$2.5 million and major capital of A$2.9 million. The major capital was significantly lower than the prior quarter (Jun qtr: A$6.2M) due to lower capital waste movement in the White Foil open pit.
The Frog’s Leg Underground mine produced 138kt of ore at a grade of 5.41g/t gold. Total development was 310m with a focus on progressing a drill drive into the hanging wall.
The White Foil open pit Stage 3 cutback progressed on plan and continued into an operating phase with volumes of capital waste declining as the strip ratio falls. Total material movement was 2.1Mt including 373kt of ore at a grade of 1.47g/t gold.
The process plant continued to perform well with 402kt of ore processed at an average grade of 2.89g/t gold. Plant utilisation was 94.6%.
A separate regulatory approval to commence development of the GRE46 exploration decline is expected to be received in the December 2018 quarter.

OPERATIONS
Mt Carlton, Queensland (100%)
Mt Carlton produced 26,197oz of payable gold comprised of 19,378oz contained in 14,223 dry metric tonnes (dmt) of gold concentrate and 6,819oz in gold doré (Jun qtr: 26,708oz, 20,908oz in concentrate and 5,800oz gold doré). AISC of A$831/oz (Jun qtr: A$712/oz) increased due to lower copper and silver by-product credits and higher sustaining capital with the construction of the Stage 5 Tailings Storage Facility wall raise. TRIF continued to improve, reducing from 3.9 to 3.8.
Operating mine cash flow of A$25.1 million and net mine cash flow of A$16.6 million (Jun qtr: A$35.2M) was generated post sustaining and major capital of A$8.5 million.
A total of 196kt of V2 ore grading 5.47g/t gold was treated. Processing plant recoveries were 87.7%. An upgrade to the concentrate thickener which was completed in July will improve plant performance going forward.
Mining continued to focus on Stage 3 ore ahead of the wet season. Permitting approval for the Stage 4 cut back is anticipated in the December 2018 quarter with pre-stripping activities planned to commence shortly thereafter.
Mt Rawdon, Queensland (100%)
Mt Rawdon produced 29,712oz of gold at an AISC of A$1,168/oz (Jun qtr: 31,244 oz, AISC A$934/oz). TRIF increased from 5.1 to 6.7 with one MTI occurring during the quarter.
Mine operating cash flow for the quarter was A$25.3 million (Jun qtr: A$27.1M). Net mine cash flow was A$11.8 million (Jun qtr: A$22.5M) post sustaining and major capital of A$13.6 million. The majority of the capital spend was on the Stage 4 cutback (A$11.0M).
Mining activities were focussed on waste material in Stage 4 and installing additional ground support in the western area of the pit.
Ore mined of 236kt at an average grade of 1.70g/t was higher than planned due to better than expected availability of ore from the bottom of the pit. The plant processed 845kt at an average head grade of 1.20g/t Au. Plant utilisation was 96%.
Over the coming two quarters the focus will continue to be on the Stage 4 cutback. Ore processed during this time will come predominately from stockpiles.
In early October 2018 the Board approved development of the Mt Carlton underground mine which will allow production from the high grade Link zone to be brought forward. Commencement of the development remains subject to regulatory approval. First ore from the underground is planned to be delivered in FY21. Capital expenditure is estimated to be approximately A$60 million of which ~A$10 million will be spent in FY19 and the remaining ~A$50 million over FY20-FY22. The FY19 component was included in prior FY19 major capital guidance of A$25 – A$30 million.

The September 2018 quarter saw all operations continuing to be cash flow positive after meeting their operating and capital needs.
A total of A$67.7 million for the FY18 final full franked dividend of 4 cents per share was paid to shareholders during the quarter.
Evolution sold 196,021oz of gold at an average gold price of A$1,662/oz (Jun 2018 qtr: 208,239 oz at A$1,675/oz). Deliveries into the hedge book totalled 37,500 oz at an average price of A$1,681/oz with the remaining 158,521oz of gold delivered on spot markets at an average price of A$1,657/oz.
Evolution generated operating mine cash flow of A$196.9 million (Jun 2018 qtr: A$221.9M). The lower cash flow was due to timing of gold sales in the September quarter and a lower realised copper price.
Net mine cash flow was strong at A$129.3 million (Jun 2018 qtr: A$136.0M). This was after investing a total of A$67.6 million in capital, split between A$27.3 million in sustaining capital and A$40.3 million in major project capital.
Cowal continued to deliver an exceptional financial performance with A$24.0 million in net mine cash flow (Jun 2018 qtr: A$5.8M) despite the heavy investment in future production via the Stage H development.
Ernest Henry net mine cash flow of A$53.8 million was lower than the June 2018 quarter, due mainly to a lower achieved copper price.
Mungari net mine cash flow of A$17.4 million was a significant improvement on the June quarter (A$3.3M) due to higher production and a lower capital spend.

EXPLORATION
– Galway Regal E46 (GRE46)
During the quarter, a program of infill drilling was completed targeting the deeps area of the GRE46 underground resource to confirm geological and grade continuity. In addition, exploration drilling targeting extensions to the system intersected high grade mineralisation 750m to the south of previous drilling on the GRE46 trend.
Infill drilling of the GRE46 underground resource identified a new zone of high-grade mineralisation associated with the Dalwhinnie Sill. The Dalwhinnie Sill is located in the footwall to the main GRE46 resource, with most historic drilling pulling up short of this position. Significant results from Dalwhinnie during the quarter include 3.0m (2.3m etw) grading 69.9g/t Au from 883m (hole 1535DD331H)[1] .
Drilling of the main GRE46 resource also returned strong results previously reported including[1] :
-
29.0m (20.1m etw) grading 5.35g/t Au from 754m and 12.0m (8.3m etw) grading 14.14g/t from 792m (hole 1535DD331G)
-
33.0m (20.8m etw) grading 3.43g/t Au from 751m and 23.0m (14.8m etw) grading 6.82 g/t Au from 806m (hole 1535DD331E)
-
24.0m (17.8m etw) grading 1.71g/t Au from 712m, 28.0m (22.9m etw) grading 3.82g/t Au from 766m and 5.0m (4.2m etw) grading 16.44g/t Au from 806m (hole 1535DD331D)

32.0m (20.1m etw) grading 2.63g/t Au from 753m (hole 1535DD331B)
-
10.0m (6.8m etw) grading 1.66g/t Au from 747m (hole 1535DD331C)
In addition, recent exploration drilling has intersected high grade mineralisation 750m to the south along the GRE46 trend. As of the end of the quarter, five drill holes were completed, with partial results received for one hole.
Drill hole 1535DD346 intersected a zone of quartz-carbonate-pyrite-chalcopyrite veining. Significant intersections for this interval were:
- 10.5m (6.8m etw) grading 11.71g/t from 362m including 2.6m (1.7m etw) grading 33.40g/t from 365 (hole 1535DD346)

E41 West
Drilling at E41 West included resource definition and resource extension drilling. Resource definition drilling focussed on infilling gaps within the current A$1,800/oz resource shell, and around the limits of the A$1,800/oz resource shell where drilling might limit the resource optimisation. A total of 16 drill holes were completed including holes for geotechnical and metallurgical test work. Significant results include:
-
8.0m (4.6m etw) grading 5.32g/t from 361m and 40.0m (22.9m etw) grading 1.03g/t from 387m (hole E41D2817)

==> picture [334 x 179] intentionally omitted <==
Figure 5: Cross section of E41D2826 showing mineralised intervals in extensional drilling below current A$1,800/oz resource shell
From resource extension drilling, high grade mineralisation in hole E41D2826 (7.7m (4.4m etw) grading 11.71g/t Au from 455m) is associated with the Killara structure, for which high grade intervals were reported in the previous quarter (19.0m (8.0m etw) grading 4.4g/t Au in E41D2811 and 4.0m grading 5.1g/t in E41D2812)[2] . The results suggest underground potential exists below the current pit resource.

Ora Banda (Perimeter and Frontier)
In the Ora Banda area significant intercepts continue to be received at Perimeter. Drilling has now intersected mineralisation along a 1,600m-long corridor. Sixteen holes were completed testing both strike and down dip extensions. In addition, a new parallel strongly mineralised structure called Frontier has been intersected in drilling 400m west of Perimeter. The area is being re-evaluated in the context of a larger scale mineral system.
Scottish Archer
Nine holes were drilled at Scottish Archer to test the extents of a high-grade zone identified in previous drilling (Figure 7 – Long Section). Best intercepts include:
-
4.0m (3.9m etw) grading 13.24g/t Au from 335m (EVRC0476)
-
1.0m (1.0m etw) grading 30.00g/t Au from 89m (EVRC0477)

Resource Definition
During the quarter 9,775m of resource definition drilling was completed across four projects. Most of the drilling occurred at Castle Hill following the restructure of ownership in July 2018. The Castle Hill project is made up of several prospects that optimise within one pit shell and a number of other satellite pits.
Castle Hill
Twenty holes were completed at the Castle Hill project. The purpose was to improve the geological interpretation and resource estimation by infilling areas not covered by historical drilling and de-risking high-grade zones near the base of the A$1,350/oz reserve pit shell. Diamond drilling also targeted resource conversion at Outridge which sits on the eastern side of the A$1,350/oz pit shell and was informed by mostly historic RC data. Best intercepts include:
Castle Hill:
-
7.2m (5.8m etw) grading 22.51g/t Au from 287m (CAHD017)
-
16.0m (14.4m etw) grading 3.87g/t Au from 80m (CAHD014)
-
1.4m (1.2m etw) grading 18.53g/t Au from 290m (CAHD011)
Outridge:
- 9.4m (7.5m etw) grading 8.55g/t Au from 67m (OUTD024)
Assay results from CAHD017 and CAHD011 returned high grades at the base of the A$1,800/oz resource shell and indicate potential upside.

Frog’s Leg
Development of the drill platform which will be utilised for drilling below the current workings has progressed well and is scheduled for completion during November 2018. Underground drilling will then commence and is expected to take approximately six weeks to complete.
Cracow, Queensland (100%)
Resource Definition
More than 13,727m of resource definition drilling was completed with three underground diamond drills focusing on resource conversion and high priority extensional underground targets. The best results were returned from the Killarney structure where mineralisation is continuing to be defined both down dip and along strike to the south of the currently defined resource.
Drummond Project, Queensland (earning 80%)
Evolution entered into an earn-in joint venture agreement with Andromeda Metals Limited (ASX:AND) over the Drummond exploration project.
Drummond is an early-stage gold exploration project located in northern Queensland covering ~520km[2] . The project is approximately 140km south of Townsville and 50km southwest of Evolution’s Mount Carlton operation (see Figure 8). Outcropping gold-bearing veins of the same style and scale to the nearby Pajingo gold-silver deposit occur within the project. Vein textures at several prospects in the project suggest the system is largely preserved, and that the most prospective level for gold mineralisation remains untested by drilling.
Key terms of the agreement:
-
Stage 1: Evolution can earn a 51% interest in the Drummond project by making a cash payment of A$300,000 to Andromeda and spending A$2 million on exploration over a two-year period
-
Stage 2: Evolution can earn a further 29% (for a total of 80%) by making an additional cash payment of A$200,000 and spending A$4 million on exploration over two years

|---|---|---|
| Criteria | Explanation | Commentary |
| Sampling techniques | •Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as downhole gamma sondes, handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. •Include reference to measures taken to ensure sample representation and the appropriate calibration of any measurement tools or systems used. •Aspects of the determination of mineralisation that are material to the Public Report. •In cases where ‘industry standard’ work has been completed this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases, more explanation may be required, such as where there is coarse gold that has inherent sampling problems, or unusual commodities/mineralisation types (e.g. submarine nodules). |
• Holes in this report consist of conventional diamond core drilling. • Drill holes were positioned strategically to infill gaps in the existing drill data set and test continuity of known lodes/mineralised structures. Collar and down hole surveys were utilised to accurately record final locations. Industry standard sampling, assaying and QA/QC practices were applied to all holes. • Prior to 2018 drill core was halved with a diamond saw in 1 m intervals, irrespective of geological contacts. Since 2018 Sampling to lithological contacts has been implemented. Oxide material that was too soft and friable to be cut with a diamond saw was split with a chisel. Core was cut to preserve the bottom of hole orientation mark and the top half of core sent for analysis to ensure no bias is introduced. RC samples were collected directly from a splitter at the drill rig. • Sample preparation was conducted by SGS West Wyalong and ALS Orange. Sample preparation consisted of: • Drying in the oven at 105ºC; crushing in a jaw crusher; fine crushing in a Boyd crusher to 2-3mm; rotary splitting a 3kg assay sub-sample if the sample is too large for the LM5 mill; pulverising in the LM5 mill to nominal; 90% passing 75 µm; and a 50g fire assay charge was taken with an atomic absorption (AA) finish. The detection limit was 0.01 g/t Au. |
| Drilling techniques | •Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc.). |
• Diamond drill holes were drilled HQ diameter through the clay/oxide and NQ diameter through the primary rock to end of hole. • All core in this report has been drilled since 2009 and has been oriented using accepted industry techniques at the time. |
| Drill sample recovery | •Method of recording and assessing core and chip sample recoveries and results assessed. •Measures taken to maximise sample recovery and ensure representative nature of the samples. •Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
• Provisions are made in the drilling contract to ensure that hole deviation is minimised, and core sample recovery is maximised. Core recovery is recorded in the database. There are no significant core loss or sample recovery issues. Core is reoriented and marked up at 1m intervals. Measurements of recovered core are made and reconciled to the driller’s depth blocks, and if necessary, to the driller’s rod counts. • There is very no apparent relationship between core-loss and grade. |

| Criteria | Explanation | Commentary |
| Logging | •Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. •Whether logging is qualitative or quantitative in nature. Core (or costean, channel etc.) photography. The total length and percentage of the relevant intersections logged. |
• Geologists log core for lithology, alteration, structure, and veining. Logging was done directly onto laptop computers via LogChief software which is validated and uploaded directly into the Datashed database. • The Cowal logging system allows recording of both a primary and a secondary lithology and alteration. Geologists also record the colour, texture, grain size, sorting, rounding, fabric, and fabric intensity characterising each lithological interval. • The logged structures include faults, shears, breccias, major veins, lithological contacts, and intrusive contacts. Structures are also recorded as point data to accommodate orientation measurements. • Structural measurements are obtained using a core orientation device. Core is rotated into its original orientation, using the Gyro survey data as a guide. Freiberg compasses and Kenometer Core Orientation tools are used for structural measurements. • Geologists log vein data including vein frequency, vein percentage of interval, vein type, composition, sulphide percentage per metre, visible gold, sulphide type, and comments relative to each metre logged. • Geotechnical logging is done by field technicians and geologists. Logging is on a per metre basis and includes percentage core recovery, percentage RQD, fracture count, and an estimate of hardness. The geotechnical data is entered into the database. • All drill core, once logged, is digitally photographed on a core tray-by-tray basis. The digital image captures all metre marks, the orientation line (BOH) and geologist’s lithology, alteration, mineralogy, and other pertinent demarcations. The geologists highlight geologically significant features such that they can be clearly referenced in the digital images. |
| Sub-sampling techniques and sample preparation |
•If core, whether cut or sawn and whether quarter, half or all core taken. •If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. •For all sample types, the nature, quality and appropriateness of the sample preparation technique. •Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. •Measures taken to ensure that the sampling is representative of the in-situ material collected, including for instance results for field duplicate/second-half sampling. •Whether sample sizes are appropriate to the grain size of the material being sampled. |
• Diamond Core is cut with a diamond saw or chisel. Core is cut to preserve the bottom of hole orientation mark and the top half of core is always sent for analysis to ensure no bias is introduced. • In 2003 Analytical Solutions Ltd conducted a Review of Sample Preparation, Assay and Quality Control Procedures for Cowal Gold Project. This study, combined with respective operating company policy and standards (North Ltd, Homestake, Barrick and Evolution) formed the framework for the sampling, assaying and QAQC protocols used at Cowal to ensure appropriate and representative sampling. • Results per interval are reviewed for half core samples and if unexpected or anomalous assays are returned an additional quarter core may be submitted for assay. |
| Quality of assay data and laboratory tests |
•The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. •For geophysical tools, spectrometers, handheld XRF instruments etc. the parameters used in determining the analysis including instrument make and |
• SGS West Wyalong and ALS Orange are utilised as primary sources of analytical information. Round robin checks are completed regularly between the two laboratories. Both labs operate to international standards and procedures and take part in the Geostatistical Round Robin inter-laboratory test survey. The Cowal QA/QC program comprises blanks, Certified Reference Material (CRM), inter-laboratory duplicate checks, and grind checks. • 1 in 30 fine crush residue samples has an assay duplicate. 1 in 20 pulp residue samples has an assay duplicate. • Wet screen grind checks are performed on 1 in 20 pulp |

residue samples. A blank is submitted 1 in every 38 samples, CRM’s are submitted 1 in every 20 samples. The frequency of repeat assays is set at 1 in 30 samples. • All sample numbers, including standards and duplicates, are pre-assigned by a QA/QC Administrator and given to the sampler on a sample sheet. The QA/QC Administrator monitors the assay results for non-compliance and requests action when necessary. Batches with CRM’s that are outside the ±2SD acceptance criteria are reviewed and re-assayed if definitive bias is determined or if re-assay will make a material difference. • Material used for blanks is uncertified, sourced locally, comprising fine river gravel which has been determined to be below detection limit. A single blank is submitted every 38 samples. Results are reviewed by the QA/QC Administrator upon receipt for non-compliances. Any assay value greater than 0.1 g/t Au will result in a notice to the laboratory. Blank assays above 0.20 g/t Au result in re-assay of the entire batch. The duplicate assays (Au2) are taken by the laboratory during the subsampling at the crushing and pulverisation stages. The results were analysed using scatter plots and relative percentage difference (RPD) plots. Repeat assays represent approx. 10% of total samples assayed. Typically, there is a large variance at the lower grades which is common for low grade gold deposits, however, the variance decreases to less than 10% for grades above 0.40 g/t Au, which is the cut-off grade used at Cowal. • Approximately 5% of the pulps, representing a range of expected grades, are submitted to an umpire assay laboratory (ALS Orange) to check for repeatability and precision. Analysis of the data shows that the Principal Laboratory is performing to an acceptable level. |

| Verification of sampling and assaying |
• The verification of significant intersections by either independent or alternative company personnel. •The use of twinned holes. •Documentation of primary data, data entry procedures, data verification and data storage (physical and electronic) protocols. •Discuss any adjustment to assay data |
• No dedicated twinning drilling has been conducted for this drill program. • Cowal uses DataShed software system to maintain the database. Digital assay results are loaded directly into the database. The software performs verification checks including checking for missing sample numbers, matching sample numbers, changes in sampling codes, inconsistent “from-to” entries, and missing fields. Results are not entered into the database until the QA/QC Administrator approves of the results. A QA/QC report is completed for each drill hole and filed with the log, assay sheet, and other appropriate data. Only the Senior Project Geologist and Database Manager have administrator rights to the database. Others can use and sort the database but not save or delete data. |

•Accuracy and quality of surveys used to locate drillholes (collar and downhole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. •Specification of the grid system used. •Quality and adequacy of topographic control. |
• All drill hole collars were surveyed using high definition DGPS. All drill holes were surveyed using a downhole survey camera. The first survey reading was taken near the collar to determine accurate set up and then at regular intervals downhole. • On completion of each angled drill hole, a down hole gyroscopic (Gyro) survey was conducted. The Gyro tool was referenced to the accurate surface surveyed position of each hole collar. • The Gyro results were entered into the drill hole database without conversion or smoothing. • An aerial survey was flown during 2003 by AAM Hatch. This digital data has been combined with surveyed drill hole collar positions and other features (tracks, lake shoreline) to create a digital terrain model (DTM). The survey was last updated in late 2014. • In 2004, Cowal implemented a new mine grid system with the assistance of AAM Hatch. The current mine grid system covers all areas within the ML and ELs at Cowal with six digits. |

• The exploration drillholes reported in this report are targeted to test for continuity of mineralisation as interpreted from previous drilling. It is not yet known whether this drilling is testing the full extent of the mineralised geological zones. All drilling prior to 2018 is sampled at 1 m intervals down hole. Lithological based sampling was implemented in 2018 with a maximum sample length of 1m and a minimum sample length of 0.3m to avoid sampling across geological boundaries. |
| Orientation of data in relation to geological structure |
•Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. •If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
• Diamond holes were positioned to optimise intersection angles of the target area. In respect of the drilling at E41W drilling is targeted to drill at right angles to the dominant vein direction however the extent of the vein package is currently unknown. • The Drilling at Galway Regal is oriented perpendicular to the known mineralised package. |
| Sample security | •The measures taken to ensure sample security. |
• Drill contractors are issued with drill instructions by an Evolution geologist. The sheet provides drill hole names, details, sample requirements, and depths for each drill hole. Drill hole sample bags are pre-numbered. The drill holes are sampled by Evolution personnel who prepare sample submission sheets. The submission sheet is then emailed to the laboratory with a unique submission number assigned. This then allows individual drill holes to be tracked. • An SGS West Wyalong (SGS) representative collects the samples from site twice daily, however, if samples are being sent to another laboratory a local freight company is used to collect the samples from site and deliver them to the laboratory. Upon arrival, the laboratory sorts each crate and compares the received samples with the supplied submission sheet. The laboratory assigns a unique batch number and dispatches a reconciliation sheet for each submission via email. The reconciliation sheet is checked, and any issues addressed. The new batch name and dispatch information is entered into the tracking sheet. The laboratory processes each batch separately and tracks all samples through the laboratory utilising the LIMS system. Upon completion, the laboratory emails Standard Industry Format (SIF) files with the results for each batch to Evolution personnel. • The assay batch files are checked against the tracking spreadsheet and processed. The drill plan is marked off showing completed drill holes. Any sample or QA/QC issues with the results are tracked and resolved with the laboratory. |
| Audits or reviews | •The results of any audits or reviews of sampling techniques and data. |
• QA/QC Audits of the Primary SGS West Wyalong Laboratory are carried out on an approximately quarterly basis and for the Umpire ASL Orange Laboratory approximately on a six- monthly basis. Any issues are noted and agreed remedial actions assigned and dated for completion. • Numerous internal audits of the database and systems have been undertaken by site geologists and company technical groups from North Ltd, Homestake, Barrick and Evolution. External audits were conducted in 2003 by RMI and QCS Ltd. and in 2011 and 2014 review and validation was conducted by RPA. MiningOne conducted a review of the Cowal Database in 2016 as part of the peer review process for the Stage H Feasibility Study. Recent audits have found no significant issues with data management systems or data quality. |

| Criteria | Explanation | Commentary |
| Sampling techniques | •Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as downhole gamma sondes, handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. •Include reference to measures taken to ensure sample representation and the appropriate calibration of any measurement tools or systems used. •Aspects of the determination of mineralisation that are material to the Public Report. •In cases where ‘industry standard’ work has been completed this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems, or unusual commodities/mineralisation types (e.g. submarine nodules). |
• Sampling of gold mineralisation at Mungari was undertaken using diamond core (surface) and reverse circulation (RC) drill chips. • All drill samples were logged prior to sampling. Diamond drill core was sampled to lithological, alteration and mineralisation related contacts, whilst RC samples were collected at 1m downhole intervals. Sampling was carried out according to Evolution protocols and QAQC procedures which comply with industry best practice. All drill-hole collars were surveyed using a total station theodolite or total GPS. • The sampling and assaying methods are appropriate for the orogenic mineralised system and are representative for the mineralisation style. The sampling and assaying suitability was validated using Evolution’s QAQC protocol and no instruments or tools requiring calibration were used as part of the sampling process. • RC drilling was sampled to obtain 1m samples using a static cone splitter from which 3 to 5 kg was crushed and pulverised to produce a 30g to 50g subsample for fire assay. Diamond drillcore sample intervals were based on geology to ensure a representative sample, with lengths ranging from 0.2 to 1.2m. Surface diamond drilling was half core sampled. All diamond core samples were dried, crushed and pulverised (total preparation) to produce a 30g to 50g charge for fire assay of Au. A suite of multi elements are determined using four-acid digest with ICP/MS and/or an ICP/AES finish for some sample intervals. |
| Drilling techniques | •Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc.). |
• RC sampling was completed using a 4.5” to 5.5” diameter face sampling hammer. Diamond holes from surface were predominantly wireline NQ2 (50.5mm) or HQ (63.5mm) holes. • All diamond core from surface core was orientated using the reflex (act II or ezi-ori) tool. |
| Drill sample recovery | •Method of recording and assessing core and chip sample recoveries and results assessed. •Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
• RC drilling sample weights were recorded for selected sample intervals and monitored for fluctuations against the expected sample weight. If samples were below the expected weight, feedback was given promptly to the RC driller to modify drilling practices to achieve the expected weights. • All diamond core was orientated and measured during processing and the recovery recorded into the drill-hole database. The core was reconstructed into continuous runs on a cradle for orientation marking. Hole depths were checked against the driller’s core blocks. • Inconsistencies between the logging and the driller’s core depth measurement blocks are investigated. Core recovery has been acceptable. Surface drilling recoveries were generally excellent with the exception of oxide zones however these rarely fell below 90%. • Measures taken to maximise sample recovery include instructions to drillers to slow down drilling rates or reduce the coring run length in less competent ground. • Analysis of drill sample bias and loss/gain was undertaken with the Overall MineReconciliationperformancewhere available. |

• Most diamond core drilled from surface was half core sampled and the remaining half was retained. In the oxide zone, where cutting can wash away samples, some surface holes were full core sampled. • All RC samples were split by a cone or a riffle splitter and collected into a sequenced calico bag. Any wet samples that could not be riffle split were dried then riffle split. • Sample preparation of RC and diamond samples was undertaken by external laboratories according to the sample preparation and assaying protocol established to maximise the representation of the Mungari mineralisation. Laboratories performance was monitored as part of Evolution’s QAQC procedure. Laboratory inspections were undertaken to monitor the laboratories compliance to the Mungari sampling and sample preparation protocol. • The sample and size (2.5kg to 4kg) relative to the particle size (>85% passing 75um) of the material sampled is a commonly utilised practice for effective sample representation for gold deposits within the Eastern Goldfields of Western Australia. • Quality control procedures adopted to maximise sample representation for all sub-sampling stages include the collection of field and laboratory duplicates and the insertion of certified reference material as assay standards (1 in 20) and the insertion of blank samples (1 in 20) or at the geologist’s discretion. Coarse blank material is routinely submitted for assay and is inserted into each mineralised zone where possible. The quality control performance was monitored as part of Evolution’s QAQC procedure. • The sample preparation has been conducted by commercial laboratories. All samples are oven dried (between 85°C and 105°C), jaw crushed to nominal <3mm and if required split by a rotary splitter device to a maximum sample weight of 3.5kg as required. The primary sample is then pulverised in a one stage process, using a LM5 pulveriser, to a particle size of >85% passing 75um. Approximately 200g of the primary sample is extracted by spatula to a numbered paper pulp bag that is used for a 50g fire assay charge. The pulp is retained and the bulk residue is disposed of after two months. • Measures taken to ensure sample representation include the collection of field duplicates during RC drilling at a frequency rate of 5%. Duplicate samples for both RC chips and diamond core are collected during the sample preparation pulverisation stage. A comparison of the duplicate sample vs. the primary sample assay result was undertaken as part of Evolution’s QAQC protocol. It is considered that all sub-sampling and lab preparations are consistent with other laboratories in Australia and are satisfactory for the intended purpose. • The sample sizes are considered appropriate and in line with industry standards. |

• Fire assay is designed to measure the total gold within a sample. Fire assay has been confirmed as a suitable technique for orogenic type mineralisation. It has been extensively used throughout the Goldfields region. Screen fire assay and LeachWELL / bottle roll analysis techniques have also been used to validate the fire assay techniques. • The technique utilised a 30g, 40g or 50g sample charge with a lead flux, which is decomposed in a furnace with the prill being totally digested by 2 acids (HCI and HN03) before the gold content is determined by an AAS machine. • No geophysical tools or other remote sensing instruments were utilised for reporting or interpretation of gold mineralisation. • Quality control samples were routinely inserted into the sampling sequence and were also inserted either inside or around the expected zones of mineralisation. The intent of the procedure for reviewing the performance of certified standard reference material is to examine for any erroneous results (a result outside of the expected statistically derived tolerance limits) and to validate if required; the acceptable levels of accuracy and precision for all stages of the sampling and analytical process. Typically, batches which fail quality control checks arere-analysed. |

• Independent internal or external verification of significant intercepts is not routinely completed. The quality control / quality assurance (QAQC) process ensures the intercepts are representative for the orogenic gold systems. Half core and sample pulps are retained at Mungari if further verification is required. • The twinning of holes is not a common practice undertaken at Mungari. The face sample and drill hole data with the mill reconciliation data is of sufficient density to validate neighbouring samples. Data which is inconsistent with the known geology undergoes further verification to ensure its quality. • All sample and assay information is stored utilising the acQuire database software system. Data undergoes QAQC validation prior to being accepted and loaded into the database. Assay results are merged when received electronically from the laboratory. The geologist reviews the database checking for the correct merging of results and that all data has been received and entered. Any adjustments to this data are recorded permanently in the database. Historical paper records (where available) are retained in the exploration and mining offices. • No adjustments or calibrations have been made to the final assay datareported by thelaboratory. |

•Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. •If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
• Drilling is planned at Castle Hill to intersect ore domains in an orientation that does not introduce sample bias. A number of orientations were drilled to target different zones of mineralisation and to assess the effect on sampling variably oriented vein sets. It has been noted that the westerly dipping vein set has not been effectively tested in some parts of the model. Evolution Mining drilled a number of holes in 2016 to the east which provided more favorable intersection angles and tested additional vein sets in some areas. Structural information gained from this program in conjunction with pit mapping has informed the search orientation and Resource classification in the estimate and will contribute to planning future drilling. Some local bias exists but in the context of a global estimate is not considered material. • Mineralisation at Perimeter is hosted in a southwest trending corridor with an average dip and dip direction of 80º /320º. • Mineralisation at Scottish Archer is hosted by northwest trending structures with an average dip and dip direction of 45º/220º. • Surface holes typically intersect at an angle to the mineralisation and there is no observed bias associated with drilling orientation. • The relationship between the drilling orientation and the orientation of key mineralised structures at Mungari is not considered to have introduced a sampling bias and is not considered to be material. • Resource Definition and Exploration drilling is typically planned to intersect ore domains in an orientation that does not introduce sample bias. A small number of holes are drilled at sub-optimal orientations to testforalternate geological interpretations. |

• Chain of custody protocols to ensure the security of samples are followed. Prior to submission samples are retained on site and access to the samples is restricted. Collected samples are dropped off at the respective commercial laboratories in Kalgoorlie. The laboratories are contained within a secured/fenced compound. Access into the laboratory is restricted and movements of personnel and the samples are tracked under supervision of the laboratory staff. During some drill campaigns some samples are collected directly from site by the commercial laboratory. While various laboratories have been used, the chain of custody and sample security protocols haveremained similar. |

| Exploration done by other parties •Acknowledgment and appraisal of exploration by other parties. • Exploration has been carried out by a number of parties including Electrum Resources NL (1985-1989), Castle Hill Resources NL (1989-1996), Goldfields Exploration Ltd (2001) and Cazaly Resources Ltd (2004-2008). The historical data and database have been reviewed by Cube and is deemed to be of acceptable quality for Mineral Resource estimation. • Significant historical work has been performed across the Regional Tenement package by numerous parties since the original discovery of gold in the region c.1890. Recent exploration commenced during the 1970’s onwards and has included exploration for base metal and gold mineralisation. |

Geology •Deposit type, geological setting and style of mineralisation. • The Castle Hill Mineral Resource comprises four deposits from south to north: Wadi, Mick Adam, Outridge and Kiora. The principal lithology to host gold mineralisation at Castle Hill is the Kintore Tonalite - a large elliptical intrusive granitoid of granodioritic composition. The tonalite intrudes a sequence of basaltic and ultramafic rocks to the east and west. The Kintore Tonalite attenuates to the south to form a narrow (80m wide in plan) intrusion which hosts the Mick Adams and Wadi gold mineralisation. Primary mineralisation within the tonalite at Mick Adams and Wadi occurs as discrete narrow west dipping quartz veins containing moderate to high gold grades and as fine disseminated gold within the tonalite groundmass. Visible gold has been observed in drill core in both quartz veins and as blebs in the tonalite groundmass. The disseminated gold is commonly associated with minor blebs of pyrite, arsenopyrite and rare chalcopyrite. High grade gold veins are typically 10 to 20cm thick and commonly occur in extensional arrays of four to five veins generating high grade zones up to 10m in horizontal thickness. Extensional veins are more common along the eastern margin of the tonalite. At the southern end of Mick Adams extensional vein arrays have been intersected in the footwall of the mafic unit proximal to the tonalite contact. Extensional shear zone arrays are also the host of the gold mineralisation at Kiora. Sheeted quartz veins are interpreted as the extensional veins propagating out from the shears. The veins within Kiora are hosted within the tonalite along the contact with ultramafic rocks and have been interpreted as having undergone supergene enrichment. Gold mineralisation at Kiora is also hosted within fault fill veins formed by movement on a shallowly dipping normal fault. Primary mineralisation within the basalt which forms the immediate hangingwall of the Mick Adams mineralisation is characteristically associated with shearing, extensional veining and biotite alteration. This mineralisation has been called Outridge and comprises a number of zones which pinch and swell along strike and down dip and has been interpreted as steeply dipping to the west. • The Perimeter and Scottish Archer prospects are located in the northern portion of the Mungari tenements, in the Ora Banda camp. The geology comprises Bent Tree Basalt and Victorious Basalt. The mineralisation is associated with structures related to the Grants Patch Fault. |

| Data aggregation methods •In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. •The assumptions used for any reporting of metal equivalent values should be clearly stated. • Intercept length weighted average techniques, minimum grade truncations and cut-off grades have been used in this report. • At Frog’s Leg composite grades of > 3 g/t have been reported. • At Castle Hill and other regional properties composite grades >1 g/t have been reported. • Composite lengths and grade as well as internal significant values are reported in Appendix. • At Perimeter and Scottish Archer, composite grades > 0.6 g/t have been reported. • No metal equivalent values are used. |
||
| Relationship between mineralisation widths and intercept lengths •These relationships are particularly important in the reporting of Exploration Results. •If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. •If it is not known and only the downhole lengths are reported, there should be a clear statement to this effect (eg ‘downhole length, true width not known’) • There is a direct relationship between the mineralisation widths and intercept widths at Mungari. • The assay results are reported as down hole intervals however an estimate of true width is provided in Appendix. |
||
| Diagrams •Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported. These should include, but not be limited to a plan view of drill hole • Drill hole location diagrams and representative sections of reported exploration results are provided either below or in the body of this report. |

| Balanced reporting •Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results • All Exploration and Resource Definition results have been reported in the Drill Hole Information Summary in the Appendix of this report. |
||
| Other substantive exploration data •Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. • A substantial Exploration and Resource Definition program is on-going at the Mungari site. Other works include field mapping and geophysical surveys. |
